Energy Performance Certificates (EPCs) give information on how to make your home more energy efficient and reduce carbon dioxide emissions. All homes bought, sold or rented require an EPC. EPC contains information on your home's energy use and carbon dioxide emissions. As well as a recommendation report with suggestions to reduce energy use and carbon dioxide emissions

EPCs carry ratings that compare the current energy efficiency and carbon dioxide emissions with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and carbon dioxide emissions would be if energy saving measures were put in place.

The rating measures the energy and carbon emission efficiency of your home using a grade from ‘A’ to ‘G’. An ‘A’ rating is the most efficient, while ‘G’ is the least efficient. The average efficiency grade to date is 'D'. All homes are measured using the same calculations, so you can compare the energy efficiency of different properties.

EPCs also provide a detailed recommendation report showing what you could do to help reduce the amount of energy you use and your carbon dioxide emissions. The report lists, suggested improvements, like fitting loft insulation and how the recommendations would change the energy and carbon emission rating of the property.

You are not legally obliged to act on the recommendations in the report. However, if you decide to do so, it could make your property more attractive for sale or rent by making it more energy efficient.
